I thought it would be really cool until I realized the whole credit thing. It often takes many permutations of a search to find the results you're looking for. If each attempt costs money and the whole thing might be a waste in the end then it's hardly worthwhile.

I've always been annoyed that Google won't search for symbols. As a programmer that makes searching for certain things anywhere from difficult to impossible. I was hopeful that this would be a search engine I could use to search for code snippets or queries that involve symbols.

Let's say, for example, that I was browsing through some PHP code and saw a double dollar sign ($$) and wanted to know what it was used for (yes, I already know, it's just an example). I might try searching for something like 'PHP $$'. This search engine is useless for that. That's the real problem I need a search engine to solve.
